To get the free nugs, all you need to do is create a Chick-fil-A account on the chain's mobile app. Once you sign in, you will receive a complimentary eight-piece nugget, either pressure-cooked or grilled. Chick-fil-A One senior lead Kaitlyn White said in a release, "We want to thank the millions of customers who have joined Chick-fil-A One on our mobile app, and this is just a small way to show our appreciation for dining with us."
